It’s ideal to have both long term and point-in-time storage features that optimize storage. Here’s a breakdown of the difference between email archiving and email backup.
Email archiving: Data archiving allows for shorter backups and a reduction in primary storage and total operating costs. (It doesn’t include other data across the network that would be needed for disaster recovery.)
Email backup: Retaining backup data is necessary for disaster recovery and compliance. This is a cloud-based, long-term, reliable storage solution that is low cost, with a fast recovery.
